METHOD OF MANAGING PLAYBACK SPEED INFORMATION OF A RECORDINGMEDIUM, RECORDING MEDIUM WITH PLAYBACK SPEED INFORMATION FOR VIDEO CONTENT RECORDED THEREON, AND REPRODUCING METHOD FOR THE RECORDING MEDIUM

摘要

The present invention relates to a method of enabling to reproduce main A/V data recorded on a high-density recording medium such as a Blu-ray Disc Rom at a playback speed suitable to the recorded main A/V data. In the present method, when main video data is recorded on a recording medium, playback spe ed information suitable to the video data is also written within a disc information table allocated in a PIC area that is located ahead of a data ar ea including the video data. The present method is efficiently applicable to a high-density recording medium containing higher-quality video data that requires higher transfer rate than a digital TV broadcast stream that requir es about 36 Mbps transfer rate.
